How to end a session in ExpressJS
Express 4.x Updated Answer
Session handling is no longer built into Express. This answer refers to the standard session module: https://github.com/expressjs/session
To clear the session data, simply use:
req.session.destroy();The documentation is a bit useless on this. It says:
Destroys the session, removing req.session, will be re-generated next request.
req.session.destroy(function(err) { // cannot access session here })
This does not mean that the current session will be re-loaded on the next request. It means that a clean empty session will be created in your session store on next request. (Presumably the session ID isn't changing, but I have not tested that.)
The question didn't clarify what type of session store was being used. Both answers seem to be correct.
For cookie based sessions:
From http://expressjs.com/api.html#cookieSession
req.session = null // Deletes the cookie.For Redis, etc based sessions:
req.session.destroy // Deletes the session in the database.
